If someone can translate that to english. It would be nice.
EDIT: already got it!
Thank you

Just to help the next guy.

1) Add furigana to the Japanese in Word (to learn how to do that see this article)
2) Highlight it
3) Hit Alt F9 and it should display code characters
4) Change 'up' to 'do' (but leave the rest of the code as is)
5) Highlight the word(s) again
6) hit Alt F9 again and it should display the word with furigana under it.
